Description

Verifies YouTube video links AND pulls the video ID from them in a matching group. Works with all capitalizations. It also matches the WHOLE link but sorts the video ID into a group.

Works with JavaScript, PHP and Python. (Not tested with any other Regex engine)

WARNING: youtu.be links have their ID group as the second group.
